FOLDING BOX.

T o all whom t may concern.

Be it known that I, CHARLES C. MILLER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Folding Boxes, of Which the following isa specification.

The invention relates to boxes and particularly to knock-down boxes adapted for use in laundries, mercantile establishments and the like for the packing of articles to be delivered or transported.

The object ofthe invention is to provide a simple and cheap box with cover, formed out of a single lsheet of materal and occupying a minimum vof space in knock.- down cover and body and the side walls of the body being adapted form, the box being readily and very quickly set up for use. Y v

The invention consists in a box having an integral cover, the side walls of both the of the box being collapsible,

togbe maintained in substantialupright position by frictional means.

In the accompanying drawings the invention is illustrated in simple form, in which- Figure. 1 is a plan view of a blank for the box; Fig. 2 a plan view of the same with the end flaps of the'body folded over on the bot.- tom of said body, the lateral .wings of said end iaps being secured to the side walls of the-body; Fig. l3 a perspective view of the box prior to being setup; Fig. 4 a plan view ofthe box set up for the deposit of articles therein; Fig. '5 a perspective View of the box in closed condition; Fig. 6 a cross-sectional view on line 6 6 of Fig. 4; Fig. 7 a crosssectional view on line 7 -7 of Fig. 6, and Fig.

-8 a cross-sectional View illustrating a modilfication of the locking flap..

Referring to the drawings, the blank indicated generally by reference character 10 is formed or stamped out of a single sheet of material such as paper board of suitable weight. At the same time that the blank is cut out it is also scored both longitudinally Vand transverselyl as shown in Fig. 1, by the broken lines. coring 11- forms a side flap 124 on the top 13 of the cover; scorings 14 and 15 form side Hap 16 constituting a common side of the cover and of the body of the v bex and scoring 17 forms side fla 18 constitutin theother side of th "bo y of the box. Soring 19 forms end flap 20 of the cover, scoring 21 formsl the oppositeend flap 2.2 of the cover, scoring 23 forms an endl w Specication of Letters Patent. Patented July 4L, 1922 Application filed April 16, 1921. .Serial No. 462,002.

- flap 24 of the body of the box andiscoring at opposite ends of end flap 24, wing 27 being4 formed by cutting through the material on the solid lines 29, 30 and 31 andby scoring 32, and wing 28 being formed by cutting through the material on solid line 33 and by scoring 34. A series of indentations 35 is formed in each wing adjacent and parallel to its obli ue edge to form on each wing a flap 36. in s 37 and 38 having flaps 39 are similarly ormed at the opposite end of the blank. The wings and flaps thereon form hinges at opposite ends of the end flaps 24 and 26. The section of the material bounded by scorings 15, 23, 17 and 25 forms the bottom 46 of the body of the box.

The end liaps 24 and 26 are longer, or extendoutwardly farther, than flaps 20-and 22.

A scoring 40 is made in flap 24 parallel to scoring 23 and substantially continuous with the outer edges of hinges 27 and 28 and forms a second flap 41 on flap' 24, the outer edge scribed, end flaps 24 and 26 are turned over on the bottom 46, the flaps 41 and 43 being carried with them, as shown in .F ig. 2. The hinges being connected to flaps `24 and 26 are now disposed on side flaps 16 and 18 and their portions 36 and 39 are secured to said side fiaps by suitable means, such as wire staples. The hinges .tend to draw the side and end flaps of the body of the box upwardly and inwardly. Flaps 41 and 43 bend on scorings 40 and 40 respectively as the endv flaps move upwardly under the inluence of the wings and their outer ends rest upon bottom 46. Hence, after the hinges are secured to the side flaps, the end fla s are inclined upwardly and inwardly and tile extension flaps 41 and 43 incline upwardly and outwardly, thus forming a crest in the end closures for ready gripping by the hands to set up the body of the box.

For packing and shipping the boxes, the cover is turned over on scoring 14 onto the bottom as shown in outline in Fig. 2. To set up a box for use the operator turns back the cover as shown in'F'1g. 3, then grasps the two crests, one in each-hand` and drawsl flaps 41 and 43 along bottom 46 toward the end flaps, and at the same time elevating end flaps 24 and 26 to vertical position. The aps 41 and 43 aremoved until their lower portions pass behind elevations 45 and abut the lower portions of the end flaps, but since in this position they are higher than the end flaps they must bend orbow toward each other in order that their lower edges shall abut the end aps. The elevations or guards 45 and the frictional engagement ,of the serrated edges of the flaps 41 and 43 upon bottom 46 lock the end flaps in upright posiend in uprlght position. After the articles -box being vcover is turned over on scoring 14 and flaps 12 2O and 22 are turned down on the e'xte are inserted inthe body of the box, upon the set up as shown in Fig. 4, the

rior of the sides and ends of they body and astring 47 is wrapped around the box and tied and the package' is then ready for delivery. y i

Insteadl of serrating the edges of fla-ps 41 and 43 I may cut out the end flaps with material extending beyond aps 41 and 43 and score the same at oints corresponding to the serrated edges, t us providing an additional flap 48 jshown in Fig. 8 which bears on bottom 46 of the body o f the box and frictionally engages the same when iap 41 is moved against end flap 24'. This frictional engagement of flaps 48 and141 with bottom 46 locks the end flap 24 inupright position.

In both constructions of frictional means the corners of the box when closed are reinforced by the several thicknesses of material locked in upright position as above described. The box is most lrapidly set up and when knocked down occupies a minimum of space. Whatl claim is:

1. A. folding box comprising a bottom section and a cover section, the bottom Section having two side flaps and two end flaps each foldable on the bottom section, each end vflap being hinged at its opposite ends to the side flaps and the hinges tending to draw all'said flaps upwardly and inwardly relatively to lthe bottom section and each A,

of the box and locks the said endl lap being of width suflicient to be foldedupon itself and to frictionally engage and brace against the bottom section for locking the said end flaps and side flaps in sub'- stantial upright position relatively' to the bottom section.

2. A folding box havin integral cover and body portions, the bo y portions comprising a bottom section, two side flaps and two end flaps each foldable on they bottom section, and` wings on the end' flaps hinged to the side flaps and' tending to drawv all said flaps inwardly, the 'cover being integral with one of the side flaps and foldable theie.- on, and each of the end flaps being of width suflicient to fold upon itself with its free outer edge in bracing frictional engagement with the said bottom for securin the end flap in upright position relative y to the bottom.

3. A folding box made from a single sheet of paper like material and including a bot' tom, side portions and end portions said side portions and end`portions being defined from the bottom by crease lines, said end portions being substantially-double the width of the side portions and .having their outer halves defined from their innerhanlves by crease tlines', said outer halves being foldable inward against the inner halves with their outer edges engaging the bottom outer halves defined from their inner halves by crease lines, said outer halves being foldable inward against the inner halves with their outer edges engaging the bottom in ,bracing relation, means connecting the ends and sides and arranged to draw the latter upward as the former4 are raised, and other means on the bottom of the box arranged to ositively engage the outer edges of they encfs and-hold the outer halves of the ends releasable in bracing position. In witness whereof I have scribed my -name 1921.
